The purpose of the study is to help older adults engage in physical exercise and also to help social engagement (opportunities to meet new people). We want to determine whether the Fittle Silver application (app) is effective in engaging older adults in physical activity and increasing social support. The Fittle Silver app is placed on a computer tablet. You are being asked to take part in this study because you are an adult over the age of 60, and are not currently engaged in a physical exercise program or in regular physical exercise activities.
